1,017,919, Specification of Letters Patent.

To all-whom itmay concern:

Be .it k1'10WI1-that'I,-SAMUEL LP... SAN nERs, a

citizen .of the United vStates, residing at. .Aurora, .-in. the countyof EHamilton and State of Nebraska, have invented certain new and usefulImprovements in Spring- 'W=heels, of'yvhich the .followingis a .speciiication.

This invention relates to vehicle wheels,- cially. to spring wheels:and-

.and pertamse manner of. making. the sameand .thElI', hubs, and s.

Thel bject of the invention is to provide in a sp' g Wheel speciallyadaptable .for automobil s,-certain novel and peculiar constructionofthe wheel huband therim A further object of the inventlon istoprovide-such novel and :peculiar connections and-combination of arts aswilLproduce a spring wheel of an-improv'ed'type, andof such'durabilitythatit will overcome many of the objections and disadvantages of other.

spring Wheels.

' A still further object ofthe invention is toprovide novel and peculiarmeans for inter(posing spiral springs between the hub. an

the rim. Various other objects, advantages and 1mproved results areattainable through and I by the construction and arrangement of upiifthe appended claim.

In the accompanying drawings forming part of this application :"Figure 1is aside elevation of a wheel -embodyingthe mvention. Fig. 2'isan'enlarged sectional view,

parts will hereinafter be described and set partly broken away. Fig. '3is a sectional view taken on theline 2-z 2. Fig. 4; is a similar viewtakenon the me y--;z Fig.

.2. Fig. 5 is a detail elevation of aspring spoke, partly broken away,and its mountings for attaching it.

The same reference numerals .denote'the same parts throughout theseveralviews of the drawings.

The wheel nowto be described is especially designed for automobiles, andis illustrated in the drawings as such, but ohviously it may be used onother'vehicles if desired, and the wheelis'so constructed that it may beoperated either as a-driving wheel or an idle wheelcarried by theautomobile. The tire 1, .of the wheel is 'concaved upon its iImer side,.and has'lateral peripheral flanges 2, to which is secured a platering3. It is zring 3, and :a partition plate-ring 4:, by means of screwbolts .5, extendi'n through :the said flanges and through-the.-r1ng4,"and screwing :into ,thebody-of the. ring" 3. ".The :rmgfl4 1s provided-.on one edge with 'an' annular vflange x 6, and: the other edge of thisring :has fitted .to it a similarmemovable flange :7 secured .in placeabysetscrews 8. These flanges extend beyond =the.ring- 3 and .overs-lapasolid'or otherru'bber tire ,9; and impinge the :latter soxas to hold iton the obvious that :tires 1 of various .thickness and elasticity maybezapplied as desired .or according 130 the .xcharacter -of the road bedover which :the wehicle is propelled.

. To therim' 1 ;is' secured a--series 10f spokes .110, which have .ascrew stud v 11, fitti-ngaperturesm the-rim and secured theretoby nuts12, having a convex washer 13,- between" the nutandthe rim.

The inner end of the spokes 1-0, has

slot .14, for rim .fianges' '15, which extend through a cushion rmg I16,suchfflanges be-= ,mg secured-in the slots-'zby bolts 'OI'LPIIIS 17,,

for :holding the rim and thering-in place.

The wheel-hub 18 has an annular central concavity '19, containinga=-body of rubber 20, forming a bumper or cushion for the bumper-ring.16, which contacts withythe cushion or bumper 20, only 'when the roador street surface creates an unevenor rough travel of the vehicle, or.upon over-loading .the same. There being suficient space between thebumper and the bumper-ring to permit ordinary vibration of the wheelwith out the engagement of the said-ring and bumper. The-ends Y of thehub are recessed so as to forma space 21, and the outer wall 22, ofthe'recesses have an annularcut-out or angular groove 23, provided withholes '24, for one-end of spiral spring spokes 25. The spokes arearranged in two sets one set for each end of the-Yhub, and the spokesets incline inwardly toward each other to the wheel rim 1, which hasholes 26, adjacent the outer end orjoining point'ofthe spokes 10, andthe rim, for the other end ofthe spring spokes. The spring spokes arecomposed of spring steel of such strength andelasticity as desired or asoccasion may demand. The innermost coil of the springs may engage thehub groove'23,-.under heavy pressure. Each end of the spring spokesisprovided with a boss or head.27, which fits a counter-sunk washer28, inthe recess-'21,

and a concaved counter-sunk washer 29, which fits within the rim 1, andthe ends of these spokes are also provided with "screw nuts 30havingsecuring pins or set screws 31.

Each end (if the hub has a plurality of tubular projections or posts 32,for bolt-rods 33,- having screw ends screwing into the body of the hub.Certain of said rods hold a capplate 34 on the inner end of the hub andagainst the postson this end of the hub, and the periphery 'of thisplate fits within the inner recess 21, flush with this end of the hub,and the axle extends through the plater34a The outer end of the hub isclosed by a plate 36 fitting the reduced end.37 of the axle 35., said'plate being secured to the may be. expeditiously assembled, @that theelasticity vor resiliency of the wheel .is enhanced owing to'the variouscushions provided therein, and that the spring spokes are augmented andrelieved of too great weight or pressure thereonby the bumper device.

It will also be observed that the ends of the spring spokes are ree towork in their bearings to the extent of their limitation by their endmountings, so that such ends may have slight lengthwise movement, incompressing and expanding the springs. I do not wish to be understood aslimiting myself to any particular material in the construction of thisWheel or the various parts thereof nor do I confine myself to anyspecial size or dimension of its parts.

Having thus'described my invention what I claim as new and desire tosecure by Letters Patent is In a spring wheel, the combination, with atread rim,-an inner rim, and spokes rigidly connecting the rims, of ahub having an annular groove, a bumper secured in the groove,"a bumperring carried by the inner rim within the said groovewith a space betweenthe ring and the hub-bumper, and a series of spiral springs on each sideof the spokes and forming the only connection between the hub and thetread rim.

In testimony whereof'I afiix my signature in presence of two witnesses.
